Root Cause

pytest is configured with filterwarnings = error, turning DeprecationWarning into a test failure; the code or a dependency still calls utcnow().

generic

中文

pytest 配置了 filterwarnings = error，将 DeprecationWarning 变为测试失败；代码或依赖仍调用 utcnow()。

Workarounds

  1. 95% success 
    from datetime import datetime, timezone
now = datetime.now(timezone.utc)
  2. 80% success 
    # pytest.ini
# filterwarnings =
#   error
#   ignore:datetime.datetime.utcnow:DeprecationWarning:legacy_lib

Dead Ends

Common approaches that don't work:

  1. 60% fail

    Hides all warnings and defeats the purpose; future breakages go unnoticed.

  2. 55% fail

    Ignores all deprecations including ones from your own code; not targeted.
